WINDOW-CLEANING CHAIR.

SPECIFICATION forming part of Letters Patent No. 764,463, dated July 5, 1904.

Applica i n fi December 15, 1903. Serial No. 185,245. (No model.)

To all whom it may concern.-

Be it known that I, HERMAN HARRIsoN, a

citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of NowYork, have invented a new and Improved Window-Cleaning Chair, of which the following is a full, clear,

and exact description.

and fastened to windows of different widths and as conveniently removed.

Another purpose of the invention 1s to provide a window-cleaning chair which will constitute a safe and firm window-seat and which will guard the occupant at the back and sides,

whether the occupant be sitting or standing.

Another purpose of the invention is to so construct the device that when not in use it will occupy but a minimum of space.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a portion of a window-frame and a perspective view of the device applied to the frame, a portion of Fig. 2 is an en- Fig. 3 is a vertical sectlon through a portion of the window-frame and the socket adapted to receive the inner terminal of a side guard of the device, and Fig. 4 1s a detail view illustrating the manner in which the standards for the seat may be hinged.

A represents a window-frame, B the outer sill thereof, and B the inner sill. The improved window-cleaning chair consists practically of two parts namely, a seat-section C and a guard-section C.

The seat (J may be made of any suitable material, wood being ordinarily used, and the said seat is generally in the form of a board of greater length than width. In connection with the seat C uprights 10 are employed located at the rear or outer longitudinal edge of the seat. Each upright 10 is threaded at its upper end and at its lower end is provided with a horizontal member 11. These horizontal or foot members 11 of the standards 10 are either securely fastened to the scat C at its under face or are removably connected therewith. Usually, however, the foot members 11 of the standardslO are secured to the under face of. the seat 0 by means of straps 12. (Shown by dotted lines in Fig. 1.)

With reference to the guard-section (1 of the device horizontal tubular heads D are employed in connection with the upper end of each standard 10. These horizontal tubular heads 1) are preferably provided with a circular enlargement 13 between their ends, and the inner ends 14 of the tubular heads 1) are interiorly threaded and are of greater diameter than the outer ends 15, the bore at the central or enlarged portion of each tubular head and at the outer end portion 15 thereof being plain or smooth, as is shown in Fig. 2. Further, in the construction of each tubular head D a socket 16 is formed at the upper portion of the enlargement 13, and the said sockets 16 are provided with set-screws 16". Further more, a set-screw 17 is located at the enlarged inner end 14: of each tubular head.

The ends of a connecting-tube 18 are secured in the inner portions 14 of the said tubular heads 1) and connect said heads, and in connection with the said tubular heads and the tubular connecting member 18 two side guards E are employed, each side guard comprising a rear member 19 and an inwardly-extending member 20 at an angle to the rear member 19. The inwardly-extending member 20 of each side guard E is provided with an outwardlyextending terminal member 21 at an angle to the inwardly extending member 20, as is clearly shown in Fig. 1.

The rear members 19 of the side guards E are passed through the bores of the tubular heads I) from the outer ends of said heads, so that the side sections or guards E may be carried inward or outward, so as to bring their inwardly-extending members 20 in close proximity to the sides of the window-frame in connection with which the chair is to be used, thus adapting the chair for use in connection with window-frames of difierent widths, and after the side members or side guards have been properly adjusted the set-screws 17,

which pass through the inner end portions of the tubular heads D and likewise through the connecting-tubes 18, are turned downward until they firmly engage with the rear members 19 of the said side guards.

is desired the sides of the window-frame may be provided with sockets 22, formed upon metal plates secured to the window-frame by screws or their equivalents, as is shown in Fig.

3, and these sockets 22 receive the terminal members 21 of the side guards E of the device. The guards above described are sufficient to protect the sides of a person when seated in the chair; but it is frequently desirable that the person should stand in the chair in order to reach the upper portions of high windows or to reach the upper portions of the Window-frame. Therefore in addition to the structure above set forth I employ an additional guard 0 and such additional guard consists of standards 10, which fit into the sockets 16, extending upward from the tubular heads D, and are provided with annular grooves 16 to receive the set-screws 16*. In connect-ion with each standard 1O I employ a tubular head D, identical in construction to the horizontal tubular heads D of the main guard C, except that the upper sockets 16 are dispensed with. The upper tubular heads D are connected by a tube 18, and set-screws 17 n are passed through the tubular heads and through thecOnneoting-tube 18. The side guards E are identical with the lower side guards E, comprisingrear members 19, which slide in the tubular heads D and in the connecting-tube 18, being held in adjusted position by the set-screws 17, and forwardlyextending outer members 20, together with terminal members 21, extending laterally in an outward direction from the intermediate members 20 The terminals 21 of the upper guard C are secured to the window-frame in the same manner as are the terminal members 21 of the lower guard C.

When the chair is not in use, the upper main guard C is removed and the side guards E, constituting portions of the lower main guard C, are dropped to the dotted position shown in Fig. 1, enabling the chair to be placed in a small compass; but if it is desirable the standards 10 may have hinged connections 0 with their foot members 11, the hinges being such as to enable the lower main guard to fold down over the seat C, but support the standards 10 in an upright position, as is shown in Fig. 4.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a Window-cleaning chair, aseat, standards extending upwardly from the rear edge portion of the seat, horizontal tubular heads attached to the standards, said heads having central enlargements and enlarged inner ends, a tubular rear guard connecting said enlarged inner ends of the tubular heads, said enlarged inwardly extending portions having their openings enlarged at their inner ends to receive said rear guard, angular side guards adjustable in said heads and the rear guard, locking devices for the side guards, carried by the heads and rear guard, and retaining members constituting outer terminal portions of the side guards.
